Abstract
A jigger dyeing apparatus comprising a liquid-draining device which is arranged in a travel passage of a spread textile fabric to be dyed between winding rolls and dyeing rolls so that a dyeing solution is squeezed out on the entire surface of the fabric uniformly with respect to the weft direction of the fabric, and a dyeing solution circulating system and a dyeing box, which are arranged so that while the fabric is being dipped in the dyeing solution, the dye concentration in the dyeing solution falling in contact with the fabric is always kept uniform in respective portions of the fabric. The problem of listing involved in conventional jigger dyeing apparatus can be completely solved by using the present jigger dyeing apparatus.
Claims10
A jigger dyeing apparatus comprising:
- a dyeing solution box having a quantity of dyeing solution therein;
- a dyeing box positioned within said dyeing solution box said dyeing box having outer edges in overflow relationship with said dyeing solution box;
- a dyeing roll within said dyeing box;
- a pair of winding rolls positioned above said dyeing box so that a web of fabric on one of said winding rolls may be unwound from said winding roll to travel downwardly through said dyeing box to pass under said dyeing roll and upwardly to be sound on the other of said winding rolls;
- an extruding pipe located above said dyeing roll;
- and
- a dyeing solution circulating system arranged to take dyeing solution from said dyeing solution box and circulate said dyeing solution to said extruding pipe to be extruded downwardly toward said dyeing roll, whereby dyeing solution will fill said dyeing box and be caused to flow along said dyeing roll and said fabric web to said outer edges of said dyeing box and overflow said dyeing box into said dyeing solution box to be recirculated, thereby maintaining a uniform concentration of dye in said dyeing solution circulating through said dyeing box in contact with said fabric.
